Why complex numbers are used in electronics?

Witryna21 mar 2024 · 2. Using complex numbers means you are trying to describe a value in a different domain and in complex number systems, the Imaginary number doesn't mean that the value of capacitor is imaginary. The imaginary number helps to signify the vector rotation when voltage is applied across it or when current flows through it. Witryna12 kwi 2004 · The simulations also show how the electrode peak in the imaginary component of impedance is shifted to lower frequencies in reducing conditions. However, the peak frequencies in the simulations are slightly lower than the observed ones. This could be because the chemical diffusion coefficient is higher than expected. how to resize brush tool in photoshop
